Exhaust gas sampling device

摘要

An exhaust gas sampling device for an internal combustion engine comprises a sampling cell (12) and an measuring gas conduit (16) for connecting said sampling cell (12) to an exhaust gas line (10) of the internal combustion engine. According to the invention said sampling cell (12) is arranged in the measuring gas conduit (16) and the measuring gas conduit is connected between a sampling point (18) of the exhaust gas line and a point within the air intake and exhaust gas outlet system of the internal combustion engine, which is at a lower pressure than the sampling point of the exhaust gas line. <IMAGE>
